AB  - Auditory event-related brain potentials (ERPs) were recorded during auditory and 
      visual selective attention tasks. Auditory stimuli consisted of frequent standard 
      tones (1000 Hz) and infrequent deviant tones (1050 Hz and 1300 Hz) delivered 
      randomly to the left and right ears. Visual stimuli were vertical line gratings 
      randomly presented on a video monitor at mean intervals of 6 s. During auditory 
      attention, the subject attended to the stimuli in a designated ear and responded 
      to the 1300-Hz deviants occurring among the attended tones. During visual 
      attention, the subject responded to the occasional visual stimuli. ERPs for tones 
      delivered to the attended ear were negatively displaced relative to ERPs elicited 
      by tones delivered to the unattended ear and to ERPs elicited by auditory stimuli 
      during visual attention. This attention effect consisted of negative difference 
      waves with early and late components. Mismatch negativities (MMNs) were elicited 
      by 1300-Hz and 1050-Hz deviants irrespective of whether they occurred among 
      attended or unattended tones. MMN amplitudes were unaffected by attention, 
      supporting the proposal that the MMN is generated by an automatic cerebral 
      discrimination process.
